The highest legitimate IQ score in the World is that of Marilyn Mach Vos Savant, who scored an IQ of 228 Terman at the age of ten, which would be equaivalent to an IQ of roughly 185 in adult age(sd=16). However, this score has been surpassed in a single case, by the legendary chess champion, Bobby Fischer, who scored an astronomic, almost impossible 190 on the Stanford-Binet in his late adolescence. To give an idea of what such score even means, consider that college graduates average 115, medical doctors and engineers average 125 and PhDs in math average 145. Imagine the difference in intelligence between a Harvard professor of mathematics and a truck driver. Well, Fischer's intelligence is as far above that of the professor as the professor's is above that of the truck driver. So until sufficient counter-evidence is presented, it is safe to assume that Fischer was the most intelligent Human in the World.
